Tl'ie denionntablef i'i-m 7 a'i'i o'y'q described is Y s :'illustrzited and described in my coj pending application No. 78,126, filed February 14,1'1916; i i The rim port-ionjfiofz-thc'whcel body. is provided at one edge With a osit ioning flange 24 against which one ge of-the. dcmountahle' rim, -7 tests, and said demoi ntalile rim is held in place by a lockin ring T he. rim; member 5 of the tyheei bodyis provided none edge with a: plurality of notches 26, sch having an undercut or inciincd wallor shoulder 27. The'10.cking ring is shaped to overlie theriin '5 and enter between the 'latter and the clemou'ntahlc rim 7, said locking ring having it flanged portionv28 thereonwvhich engages '100 the side of the demountabic riinland holds itin position. "l.his locking ring is also provided with locking projections- 30 which have inclined walls 31- miztpted to engage the inciincd shoulders 27.- Thekicking ring 25 is applied laterally to the wheel withthe projwtions 3O entering-the notches 26'- and when said locking ring is Ln piace'it is given a turning .movemcnt to carry 7 the shoulders of the projections 30 d! the shoulders 27 of the notches 26, thus holding the locking ring in place. To remove the demountable rim the locking ring sustained ina bearing member 34 secured to the rim member 5. This actuating lever has a n0se 36 which is-rece ved in a notch 37 in the locking ring, this notch being herein shown as formed bythe space between two pro ectlons 38. The locking ring 25 can thus be givenitslocking and unlockin movement by simply turning the actuating lever 32 in one direction or the other. The locking ring is an expansible and contract-ible ring and when in position it encircles theedge of the rim 5, as seen in Fig. 2. The locking movement of the locking ring operates-to contract it against the outerfaceof the rim 5, as well as to move it into its locking position, and the unlocking movement of the ring operates to expand it so that it can bereadily removed' The capability of expanding and contracting is providedfor by making the ring a spl t ring. One end of the ring is shown asprovided witha slot 50 in which operates a stud 51 extending from the other end of the ring, the stud and slot permitting an expanding or contracting movement to the locking ring. When the locking ring is put into positioni'and is turned into locking position by the lever 32, the projections 30 will not only be drawn intothe notches 26,;biit-the lockingring will be contracted and drawn tightly about the rim 5.

Fig. l showstthe parts in the position they occupyfwhenlthe :locking ring is locked in position, 'and to holditin this position, I have provided a lever locking member 39 which is mounted on a stud 40 secured to the rim 5 and is heldin place thcreon'by a locking nut 41. This locking member 39 engages the end of the lever 32 and thus holds it from turning. movement. To unlock the lever 32 the nut 41 is'loosened t0 permit-the'locking member 39fto be swung laterally out of engagement with the lever 32 after which the lever 32 can be turned to unlock the locking ring" The bearing block 31% is shown as adjustably secured to the rim 5, the purpose of this being to pro vide'for adjustment as wear. occurs.
